Cores for thought : Structural and spectroscopic studies show that the {Cu 2 (S 2 ) 2 } 2+ core of [Cu 2 (tmeda) 2 (μ‐S 2 ) 2 ](OTf) 2 (tmeda= N , N , N′ , N′ ‐tetramethylethylenediamine; OTf=trifluoromethanesulfonate) is best described as a bis(μ‐disulfido( . 1−))dicopper( II ) complex rather than a bis(μ‐disulfido(2−))dicopper( III ) complex. This complex represents a new motif in the copper–sulfur chemistry of biologically relevant, synthetic model systems.
